Laura's piece features a series of anecdotes on how women are
pooping at work without getting caught.

Here's an excerpt:

One 27-year-old at a financial services firm in New York
City brings her BlackBerry along while she does it, and sends an
email during the experience so that she has an “alibi.” A
popular national morning TV show host in her 40s—who, like most
others interviewed in this story, asked to remain nameless to
avoid embarrassment—said that she walks 10 minutes to another
section of her midtown office building to do it, and still then
only does it when no one in the hallway sees her en route.

And another:

Jill, 28, a Vancouver native now working at an insurance company
in New York City, said that if she absolutely can’t avoid the act
entirely, she lifts her feet off the ground and props them up
against the side of the stall to avoid the “chance that the
person next to me would recognize my shoes and forever hold in
their heads that I was the girl” defecating in the ladies’ room.
